Biology: Mitosis And The Cell Cycle Quiz! - Quiz

Hey fellas, welcome to a short mitosis quiz. As you already know that mitosis is a process of cell division and the creation of two identical daughter cells.
In this quiz, there are 8 basic questions on mitosis, so, answer and see how much you score.


Questions and Answers
  • 1. 

    What is the name of the attachment point between sister chromatids in a chromosome?

    • A.

      Centrioles

    • B.

      Centromeres

    • C.

      Spindles

    • D.

      Membranes

    Correct Answer
    B. Centromeres
    Explanation
    Centromeres are the attachment points between sister chromatids in a chromosome. During cell division, the centromere plays a crucial role in ensuring that the sister chromatids are properly separated and distributed to the daughter cells. It serves as a binding site for proteins that form the spindle fibers, which help in the movement of chromosomes. Centrioles, on the other hand, are involved in cell division but are not directly related to the attachment of sister chromatids. Spindles and membranes are also not specifically associated with the attachment point between sister chromatids.

    What is the name of the microtubule fibers that pull the sister chromatids apart?

    • A.

      Centromeres

    • B.

      Membranes

    • C.

      Ligands

    • D.

      Spindles

    Correct Answer
    D. Spindles
    Explanation
    Spindles are the microtubule fibers responsible for pulling the sister chromatids apart during cell division. These fibers attach to the centromeres of the chromosomes and exert force to separate the sister chromatids, ensuring that each daughter cell receives a complete set of chromosomes. The other options, centromeres, membranes, and ligands, are not directly involved in the physical separation of sister chromatids during cell division.

    The pinching off of the cell membrane that creates two new cells (after mitosis) is called:

    • A.

      Interphase

    • B.

      Metaphase

    • C.

      Anaphase

    • D.

      Cytokinesis

    Correct Answer
    D. Cytokinesis
    Explanation
    Cytokinesis is the process in which the cell membrane pinches off to create two new cells after mitosis. This is the final stage of cell division, where the cytoplasm and organelles are divided equally between the two new cells. Interphase, metaphase, and anaphase are all stages of mitosis, but they do not involve the physical separation of the cell membrane to create new cells.

  • 4. 

    Which phase of mitosis is shown in the picture?

    • A.

      Anaphase

    • B.

      Metaphase

    • C.

      Prophase

    • D.

      Telophase

    Correct Answer
    B. Metaphase
    Explanation
    The correct answer is metaphase because in the picture, the chromosomes are aligned along the equatorial plane of the cell. This is a characteristic feature of metaphase in mitosis, where the chromosomes are fully condensed and positioned at the center of the cell before they separate and move towards opposite poles during anaphase.

  • 5. 

    Which phase of mitosis is shown in the picture?

    • A.

      Prophase

    • B.

      Telophase

    • C.

      Anaphase

    • D.

      Metaphase

    Correct Answer
    B. Telophase
    Explanation
    The correct answer is telophase. In telophase, the chromosomes have reached opposite poles of the cell and are starting to decondense. The nuclear envelope begins to reform around each set of chromosomes, and the nucleolus reappears. Cytokinesis, the division of the cytoplasm, also begins in telophase. The picture likely shows these characteristics, indicating that it is in the telophase stage of mitosis.

  • 6. 

    Which phase of mitosis is shown in the picture?

    • A.

      Telophase

    • B.

      Metaphase

    • C.

      Anaphase

    • D.

      Prophase

    Correct Answer
    D. Prophase
    Explanation
    The correct answer is prophase because in the picture, the chromosomes are condensed and visible, the nuclear membrane is starting to break down, and the spindle fibers are forming. This is characteristic of the prophase stage of mitosis.

    Which phase of mitosis is shown in the picture?

    • A.

      Anaphase

    • B.

      Prophase

    • C.

      Telophase

    • D.

      Metaphase

    Correct Answer
    A. Anaphase
    Explanation
    The correct answer is anaphase. Anaphase is the phase of mitosis where the sister chromatids separate and move towards opposite poles of the cell. In the picture, it is likely that the chromosomes are seen being pulled apart and moving away from each other, indicating anaphase.

    What is the name of the structures responsible for generating the spindle fibers?

    • A.

      Centromeres

    • B.

      Membranes

    • C.

      The funky hot chocolates

    • D.

      Centrioles

    Correct Answer
    D. Centrioles
    Explanation
    Centrioles are the structures responsible for generating the spindle fibers. Spindle fibers play a crucial role in cell division, specifically in the process of separating chromosomes during mitosis and meiosis. Centrioles are found in pairs and are located near the nucleus of animal cells. They organize the microtubules that make up the spindle fibers, which attach to the centromeres of chromosomes and help in their movement and alignment.
